Trifluoroacetic acid (5 mL) was added to a solution of [3-[6-chloro-5-[(cyclohexylacetyl)amino]-2-quinolinyl]propyl]carbamic acid, 1,1-dimethylethyl ester (Example 23(a)) (0.9 g) in dichloromethane (15 mL). After stirring for 2 hours the solvent was removed under reduced pressure and the resulting residue was purified (Varian Chem elute cartridge with dichloromethane as eluant). Further purification (Varian SCX cartridge using methanol (100 mL) and then 10% ammonia in methanol (100 mL) as eluant) afforded the title compound (300 mg).
